Task‐Related Aperiodic EEG (1/f) Activity in Autism

Autism Research, EarlyView.
ABSTRACT Autism has been hypothesized to involve atypicalities in the balance between neural excitation and inhibition (E/I). Aperiodic EEG activity, characterized by the 1/f exponent of the power spectrum, provides a proxy of cortical E/I dynamics. However, prior studies in autism report mixed findings regarding the slope of aperiodic activity.

Decarbonization Boundary Choices and the Effectiveness of Stakeholder Engagement in Voluntary Climate Action Commitments: Evidence From Emerging Economies

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how stakeholder engagement, conceptualized as a boundary‐spanning organizational capability, interacts with firms' decarbonization strategies, in relation to climate action commitments (CACs) in voluntary initiatives.

A Non-Intrusive Stochastic Isogeometric Analysis of Functionally Graded Plates with Material Uncertainty

Axioms, 2020
A non-intrusive approach coupled with non-uniform rational B-splines based isogeometric finite element method is proposed here. The developed methodology was employed to study the stochastic static bending and free vibration characteristics of ...

A Simple, Dynamic Geometric Phantom for MRI and CT Reconstruction Pipelines: Beyond Shepp–Logan

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT A customizable, dynamic geometric phantom was developed to bridge the gap between simplistic static phantoms and highly realistic, complex 4D solutions. The phantom enables initial testing, helps detect implementation errors, and supports quantitative evaluation of new dynamic acquisition and reconstruction methods.

Efficient Local Refinement near Parametric Boundaries Using kd-Tree Data Structure and Algebraic Level Sets

Algorithms, 2022
In analysis of problems with parametric spline boundaries that are immersed or inserted into an underlying domain, the discretization on the underlying domain usually does not conform to the inserted boundaries.

Revealing Nafion‐Induced Copper Modifications by Combining In Situ and Ex Situ X‐Ray Absorption Spectroscopy

Small, EarlyView.
This work elucidates that Nafion alters Cu‐based CO2RR catalysts by promoting partial Cu dissolution and stabilizing Cu2+ species through coordination with sulfonate (‐SO3−) groups. Combining in situ Cu L‐edge with ex situ Cu K‐edge XAS measurements, the study highlights how Nafion primarily modifies the nanoparticle surface, while less oxidized Cu ...

A Multi‐Agent Bidding Strategy in Day‐Ahead Joint Energy and Reserve Markets Considering Risk Preferences

IET Smart Energy Systems, EarlyView.
A PER‐MATD3‐based bidding model for generators in day‐ahead joint energy and reserve markets is proposed. An aggressiveness coefficient quantifies risk preference, KAN improves interpretability and simulation results demonstrate enhanced coordinated decision‐making and training stability.

Transient analysis of laminated composite plates using NURBS-based isogeometric analysis

Vietnam Journal of Mechanics, 2014
We further study isogeometric approach for response analysis of laminated composite plates using the higher-order shear deformation theory. The present theory is derived from the classical plate theory (CPT) and the shear stress free surface conditions ...
